Building a 5.1 channel amplifier

[shashankbr]

Hi everyone!

I had an Altec Lansing FX5051 system and its amp has gone bad. I m not able to get it repaired from anyone, so I have decided to design my own amp for the speakers which are btw awesome.

Front/Rear Left/Right - all four are 12W @4ohms, 10%THD
Center - 13W @4ohms, 10% THD
Subwoofer - 28W @8ohms, 10%THD

Can you please direct me to some links or give me some ideas on starting with this project?
I would preferably want to design a solid state or chip amp.
Also, how much more power can I pump into these speakers?
What are the ICs that I can use & where will I get the circuit diagram for this design?

Plz help me out. My PC is without speakers for around 4 months

I hope this will get you started. For one thing is sure that you have to understand Analog filters first and their type and response type then you can got to digital filtering.

Thanks for the links...
I am not in audio building stuff too. But necessity is the mother of invention right??
I have some idea about the filters as I am an Electronics engg student.
